In an organic light-emitting display panel and an organic light-emitting display device, lighting lines arranged in the organic light-emitting display panel to be used for lighting inspection are connected to portions of power lines arranged in the organic light-emitting display panel, in which a voltage drop occurs. In a display driving period, a voltage the same as a voltage applied to the power lines is applied to the lighting lines. Then, the lighting lines can be used as auxiliary power lines, so that additional lines for compensating for the voltage drop are not required. Power compensation is enabled without increasing the voltage applied to the power lines. The uniformity of images can be improved without increasing power consumption.

A curved display device including a display area and a non-display area is provided. The curved display device includes a first direction area configured to maintain a flat state and a bending area connected to the first direction area. A thin film transistor (TFT) layer, a passivation layer, a sealing layer, and an upper film are provided on a base substrate in an area where the display area overlaps the bending area, and the sealing layer and the upper film extend to an area where the non-display area overlaps the bending area.
